I have 295/75/16 Nitto Terra Grapplers on ion alloy wheels. One of my buddies wants to trade me for 33/13.5/15 Mud Grapplers on Black Crager bullet hole wheels. I need some advice on whether I should trade or not. If that wide tire will hurt gas mileage a lot and how it will be offroading. If anybody could give some advice I would really appreciate it. Thanks I need to know quick also!

Can't say as to off road performance or an ride quality as I've never had them but you can bet on two thing. 1) They will be LOUD. 2) You won't be able to keep you jeep clean. At all. They will sling dirt, rocks, mud, muddy water, and water else they can find all over you Jeep. It's all personal preference though.

EDIT: plus I like the ions better. ( I'm biased because I have those )
